Invensys’ Wonderware Business Unit Announces New Systems Integrator Program Tier for FactorySuite A² – Built On ArchestrA

New Program Tier Recognizes Market Leaders Proficient In Applying ArchestrA Architectural Approach for Creating Open Industrial Automation & Information Solutions

LAKE FOREST, Calif., July 11, 2003 -- Wonderware, a business unit of Invensys Systems, Inc., today announced the new FactorySuite A²™ Certified Systems Integrator (SI) program tier for systems integrators utilizing FactorySuite A² configurations that are built on ArchestrA™ technology.

The new tier recognizes systems integrators that have completed specialized training designed to provide the skills necessary to effectively implement ArchestrA-based Wonderware® FactorySuite A² solutions featuring the Industrial Application Server and have implemented FactorySuite A² projects in the field.

The new FactorySuite A² certification level is Wonderware’s newest and most prestigious addition to its successful systems integrator program. Existing program tiers have recognized registered systems integrators and, at a higher level, certified systems integrators who have achieved certification on one or more products within Wonderware® FactorySuite® products.

All three current program tiers are intended to help customers and distributors identify SIs that have the appropriate skills to develop integrated solutions for their specific applications.

The FactorySuite A² Certified Systems Integrator program tier provides additional business growth and profitability opportunities for SIs by recognizing proficiency in FactorySuite A2 system integration.

By using the ArchestrA Integrated Development Environment (IDE) and ArchestrA Object Toolkits, SIs and customers are able to take advantage of unprecedented levels of project engineering productivity and software re-use. These capabilities reduce the cost and time of developing and deploying new projects, as well as reduce the need for ongoing maintenance, updates and expansion.

“End users and plant owners who want to reap the productivity and ongoing lifecycle cost improvements of products built on ArchestrA technology will have access to a pool of talented systems integrators who have been trained to maximize the benefits of ArchestrA technology,” said Mark Davidson, vice president of ArchestrA marketing for Invensys.

“The new program tier provides systems integrators with a credential that recognizes their enhanced capability to work with Wonderware products that are built on ArchestrA technology.”

The ArchestrA architecture is an open framework for creating industrial automation and information products, applications and services. It includes an industrial applications development platform on which customers, OEMs, systems integrators, third-party developers and Invensys can develop efficient and competitive production systems. The ArchestrA architecture enables the re-use of engineering, which significantly reduces the cost and time of developing new projects. The total cost of ownership for projects is reduced as well, since using this architectural approach facilitates easier extension and expansion of current and legacy plant systems with the latest Microsoft.NET technology so that production operations stay competitive.
